started grow question 3y ago
My autos are turning into flowering. It seem I’m under led, respecting the grow schedule and new leaves are turning light green… is it normal or a deficiency/excess (iron?) ? Thank you for the answers

This is absolutely normal.. all new growth is that light green and it will darken up to "normal" as it gets older... no worries!

Light stress or Nute Problem??
Would this be a light stress problem or a nutrient problem? Seems to be only the ones on the top so I'm guessing lights but want to be sure.

Yellow bottom leaves/brown spots on bottom leaves
Hi guys, So 4 or 5 bottom leaves of my 7thWeek autoflower looked like this and I ripped them off. Is that ok or did I harm her? Anyway, is that a Calcium def? Should I give her some CalMag? Could it be something else? Besides this, the general condition of the plant is good. Tx!

Leaves fading and dying, started from bottom but spreading
I’m starting to be at a loss with this. Calmag issues earlier in veg, seemed to improve for a while but now bottom leaves started to die - I thought this was just due to beginning of flower but it’s getting worse and spreading even to healthier new growth. PH (should be) fine.

Hey guys and gals, on week 4 of this indoor, hydro grow and I just hit this plant 5 days ago with fox farms sledgehammer for its first flush. Before this, the plant was growing very well. Is this due to the flush? Should I flush in tap water before next feed? Thx for the help ^^

Leaves keep turning brown and yellow
It all begann with what I thought was light burn. I then considered it CalMag deficiency. Giving it CalMag did not stop it. My current guess is too low pH due to strip inaccuracies, so I gave it around 8 today instead. What do you recon, why could it keep getting worse?
